Gd. Peng et Pl. Chu, DESIGN AND FABRICATION OF BIREFRINGENT SPLITTABLE COMPOSITE (BISPEC) FIBER FOR POLARIZATION-MAINTAINING DEVICES, Electronics Letters, 30(8), 1994, pp. 666-667
The authors propose a new type of fibre, the birefringent splittable c
omposite (BISPEC) fibre designed for polarisation maintaining optical
devices. In addition to the good polarisation axis alignment (within 1
-degrees), this fibre has the added important property that it can rea
dily be split to allow for standard fibre connection by fusion splicin
